#  paths: An Imputation Approach to Estimating Path-Specific Causal Effects 

 



In causal mediation analysis with multiple causally ordered mediators, a set of path-specific effects are identified under standard ignorability assumptions. This package implements an imputation approach to estimating these effects along with a set of bias formulas for conducting sensitivity analysis (Zhou and Yamamoto <[*doi:10.31235/osf.io/2rx6p*](https://doi.org/10.31235%2Fosf.io%2F2rx6p)>). It contains two main functions: paths() for estimating path-specific effects and sens() for conducting sensitivity analysis. Estimation uncertainty is quantified using the nonparametric bootstrap.
